Name: Homemade amplifiers low frequency.
It contains a description of several amateur low-frequency amplifiers - from the simplest single-tube amplifier, which can be manufactured by a radio amateur who is starting to assemble an amplifier for the first time, to more complex ones intended for manufacturing in radio circles, such as an amplifier for a school radio center.
The first chapter, intended for beginner radio amateurs, contains general information about amplifiers. Chapters two and three cover tube and transistor amplifiers.
The book is intended for a wide range of radio amateurs.
The vast majority of radio amateurs begin their acquaintance with radio technology with low (audio) frequency amplifiers. This is explained by the fact that a neatly assembled, simple amplifier usually starts working immediately, without any adjustments, giving the novice amateur his first joy. In addition, a simple amplifier is usually available for self-production by amateurs with insufficient theoretical knowledge and practical experience which do not allow them to take on the construction of a more complex radio-technical device.
This way of getting acquainted with radio engineering is the most correct, since familiarity with the operation of the amplification stage and its study are necessary for understanding the principle of operation of any radio device. With rare exceptions, all radio equipment (receivers, televisions, tape recorders, etc.) mainly consists of various amplification stages (cascade or a stage is a lamp or transistor and related circuit elements). Therefore, it is important that a novice radio amateur understands from the first steps the physical essence of the operation of the amplifier stage and approaches the design of the amplifier consciously, without blindly copying randomly encountered circuits.
